A good PCB layout for the CWX813-025.0M involves keeping the input and output traces separate, using a solid ground plane, and minimizing the distance between the oscillator and the load. A 4-layer PCB with a dedicated ground plane is recommended.
To ensure reliable startup, make sure the power supply is stable and has a low noise floor. Also, ensure the oscillator is properly terminated, and the load is within the recommended range. A slow power-up ramp can also help.
The CWX813-025.0M is rated for operation from -40°C to +85°C. However, it's essential to consider the specific application's requirements and ensure the oscillator is properly cooled or heat-sunk if operating at high temperatures.
While the CWX813-025.0M is a robust oscillator, it's still susceptible to vibration-induced frequency shifts. To mitigate this, consider using a vibration-dampening material, such as a gel-based adhesive, to secure the oscillator to the PCB.
To troubleshoot frequency drift or instability, check the power supply voltage, temperature, and load impedance. Ensure the oscillator is properly terminated, and the PCB layout is optimal. Also, verify that the oscillator is not subjected to excessive vibration or electromagnetic interference.
